Local VLANs are now recommended over end-to-end VLAN implementations. A trunk is a Layer 2 point-to-point link between networking devices carry the traffic of multiple VLANs. ISL and 802.1Q are the two trunking protocols that can connect two switches. VTP is used to distribute and synchronize information about VLANs configured throughout a switched network. VTP pruning helps to stop flooding of unnecessary traffic on trunk links. Device communication within the same VLAN can be fine-tuned using pVLANs. A pVLAN is associated to a primary VLAN, and then mapped to one or several ports. A primary VLAN can map to one isolated and several community VLANs. pVLANs can span across several switches using regular 802.1q trunks or pVLAN trunks. Use EtherChannel by aggregating individual, similar links between switches. EtherChannel can be dynamically configured between switches using either the Cisco- proprietary PAgP or the IEEE 802.3ad LACP. EtherChannel load balances traffic over all the links in the bundle. The method that is chosen directly impacts the efficiency of this load-balancing mechanism.
